In Vedic astrology, Kundli Matching (also called Gun Milan or Ashtakoota matching) compares two birth charts across 8 categories totaling 36 points: Varna (caste), Vashya (dominance), Tara (destiny), Yoni (nature), Graha Maitri (friendship), Gana (temperament), Bhakut (love), and Nadi (health). A score of 18 or above out of 36 is generally considered favorable for marriage.
